I’m in Cork, mainly for the excellent Social Network Portability event on Sunday, but am also staying through Blogtalk’08 which has been great. I’ve uploaded my slides from my talk (slideshare in Flash, included inline here, or a pdf). I have some rough speaking notes too,  maybe I’ll get those online. I have no idea how they relate to whatever actually came out of my mouth during the talk :) Apologies to those without PDF or Flash. I haven’t tried Keynote’s HTML output yet.

Basically much of what I was getting at in the talk, and my thoughts are only just congealing on this … is that the idea of a ‘claim’ is a useful bridge between Semantic Web and Social Networking concerns. Also that it helps us understand how technologies fit together. FOAF defines a dictionary of terms for making claims, as does xfn, hCard. RDF/XML, Microformats, RDFa, GRDDL define textual notations for publishing documents that encode claims, and SPARQL gives us a way of asking questions about the claims made in different documents.
